Diving the Yongala

[Bombay High]

I was nauseous with a pounding headache, thanks to the rocking boat. I knew getting into the water would help.

It sounds like it maybe CO2 retention from the description of your breathing pattern

Something to maybe consider is a sinus reverse squeeze. I have had it once while doing a DDC deco. At depth I had no problem, but when they started blowing us up, I felt like my head would explode. It felt like my head was being held in a clamp and someone was relentlessly turning the screw. I felt disorientated and nauseous. They had to blow me down, administrate a decongestant and start again. I felt no congestion, or any clue that said sinus, so I had no idea where it came from. Its never happened again.

I'm not in any way an experienced diver, but If I felt my regulator wasn't delivering enough air, I would try my Occy, then try any offered reg from my buddy. If the Occy was better, thumb the dive, if my buddies felt better, ask them to check my tank is on properly, and if so thumb th dive.

If all three felt the same it would rule out any kind of equipment issue.

Is there a reason you stuck with the reg that you felt wasn't giving you enough air?

One thing I do not understand is why did they not tie off to the other end of the wreck? That way you would start the dive against the current and go back with the current. If you get tired on the way you can always drift back to the line.
It also concerns me than no one was keeping an eye on the water and did not notice you coming up. In case you let go of the line would he have seen you?

I have been on the same boat on the Yongala and it was done the way I described and even though the currents were too strong for some to make it all the way to the other end of the wreck everyone had a nice safe dive. We actually helped some divers from another boat (tied off to the other end of the wreck) as they surfaced and drifted past us. Their boat did not know that they were missing some divers untill we brought them back to their boat.
